Yes, Ruby is slower than C most/all of the time, but that doesn't mean you can't do great things with Ruby. For example, there are desktop applications written in Ruby. Checkout FreeRIDE as an example of what can be done. http://freeride.rubyforge.org/ About the possibilities of Ruby, i know Ruby is a generic language, and > that we can program almost every software in Ruby, but *almost* every > for example, is it possible to develop a peripheral driver in Ruby ?? > more generally to access the hardware ? to write a linux kernel module > ?? ( i guess it is not possible to write a ruby OS kernel ) You may want to check out Ruby USB. It is a Ruby library that wraps libusb. Michael Hewner presented a session on it at the MountainWest RubyConf (hope to have video released soon) where he connected to and communicated with USB devices. I believe the library he used is found here: http://www.a-k-r.org/ruby-usb/ There may be more information about Ruby USB on his blog, but it has the word "fetish" in the domain so I can't view it from work. :S http://technofetish.net/buffaloblog/ thank you > > ( i'm not a native english speaker, sorry if any mistakes ) > > -- > Posted via http://www.ruby-forum.com/. > > ------ art_36709_24310260.1175717656399--
